[mythtv-users] Remote mythfrontend displays no video

[David Won]

Hey all. I have a problem now. Everything was working fine but now it
doesn't. I've been updating the CVS and I also upgraded my laptop to RH
9/ I'm not sure which one caused the problem. I'm running mythback on
the main PC and everything works great. The problem is when I try to run
the frontend on my laptop. It used to work fine but now whenever I try
to play something I don't get the video. iptraf shows lots of data being
transferred but I just see the movie selection screen. The only way to
get out is to kill it which usually kills the backend. Any ideas?

I tried running gdb mythbackend and frontend but didn't get much/ Not
sure if I'm doing it right.

here is the output anyways.
